DOOR-CLOSING SPRING.

Specification of Letters Patent. Patented Jan, 18, 19:10,

Application filed July 16, 1909. Se1ial`No..508,01'7.

springs, and has for an object to provideV av device of this character wherein will beemployed novel and effective means adapted for engagement at one end with the gate or closure and at the other end vwith a portion of a fence or the like, and which when operatively applied will effectively hold the gate normally in its closed position.

A still further object of my invention is to provide a spring of the above stated character that will be extremely simple in construction and which may be manufactured at a relatively low cost.

The above mentioned and other objects are attained by the construction, combina-l tions and arrangements of parts, as disclosed on the drawing, set forth in this specifica-k tion, and particularly pointed out in the appended claim.

In the drawing, forming a portion of this specification and in which like characters of reference indicate similar parts in the several views: Figure l is a front view of a gate and a portion of a fence showing my improved gate spring in its applied position. Fig. 2 is a detail elevation of the spring. F ig. 3 is a detail horizontal section taken on the line 3 3 of Fig. l.

Upon reference to the drawing, there is shown a gate A which is hinged to the post B of a fence structure C. A bracket or retaining member 1 is secured by means of fastening devices 2 to the panels or to any other part of the fence structure at a pointadjacent to the post B. This bracket or re-V taining member preferably comprises a plate which is formed with a longitudinally extending boss 3 1n which is formed a groove 4f. The groove communicates at one endV with a recess 5 formed 1n the boss and at the other end the groove opens directly onto the bracket or `retaining member.

Adjacent to one end of the boss 3, the plate forming the bracket is provided with anoutwardly extending lug or stop shoulder 6 which is adapted to form with 1the boss 3 a guide channel 7. y A bracket or retaining member 8 is secured to the panels of the gate A, and as shown, the said bracket o-r retaining member vis identical in con struction with the bracket or retaining member l and it is thought that the debody portion of the plate forming the said scription of the former will sufiice for the latter.

A spring 9 is provided and is preferably formed from a plurality of twisted steel wires whose ends are bent to form fingers 10 which are engaged at their extremities in the recesses 5 formed in the bracket plates or retaining members. The upper and lower portions of the springs adjacent to the 'inner ends of the fingers are disposed in the guide channels 7 upon the brackets or retaining members. In practice, the spring forming lwire is first bentinto the form shown in Fig. 2 and one extremity or finger of the wire 1s operatively positioned in the lowermost bracket or retaining member. After this operation4 thev wire is extended diagonally and its upper extremity orfinger is operatively connected with the upper-l most bracket or retaining member and isv given a half turn in the recessy 5.

manner more resiliency is offered the spring In this as will be appreciated. The spring as here-v in-shown and describedwill be found extremely simple in construction, it may be placed upon the market at a rela-tively low cost and its use provides means whereby the passage with an outwardly extending lug,Vx

and a spring connecting the said brackets and provided at its ends with oppostely extending ngers, said fingers being arranged in the recesses formed n the said brackets and engaged with the lugs whereby the fingers are held from longitudinal movement.

In testimony whereof I afx my signature 1n presence of two witnesses.
